Abstract

La presente invención se refiere a un sistema de control de una óptica motorizada de distancia focal variable (3) basado en una tarjeta electrónica (2) conectable a una de las ranuras de expansión de un ordenador (1), con la finalidad de controlar el posicionamiento de la distancia focal y el enfoque correspondiente. La tarjeta desarrollada (2) consiste en una etapa de control (2.1) que permite el ajuste de la distancia focal seleccionada y el enfoque correspondiente de una óptica para cámara de video, mediante el accionamiento de los respectivos motores (2.3) que presenta la óptica. La realimentación del lazo de control (2.4) posibilita el ajuste preciso y proporciona información al usuario de la posición ocupada. El sistema se comunica con un ordenador a través de un interfaz (2.2), concediendo un modo de funcionamiento automático o bien, guiado por un operador. Puede destacarse su uso en aplicaciones de seguridad o vigilancia, control de calidad, teleoperación de sistemas robotizados y teleconferencias.The present invention refers to a control system of a variable focal length motorized optics (3) based on an electronic card (2) connectable to one of the expansion slots of a computer (1), in order to control the focal length positioning and corresponding focus. The developed card (2) consists of a control stage (2.1) that allows the adjustment of the selected focal length and the corresponding focus of a video camera lens, by operating the respective motors (2.3) presented by the lens . Feedback from the control loop (2.4) enables fine adjustment and provides information to the user of the occupied position. The system communicates with a computer through an interface (2.2), granting an automatic or operator-guided mode of operation. Its use in security or surveillance applications, quality control, teleoperation of robotic systems and teleconferences can be highlighted.
